Selena Gomez shocked her fans when she showed up at the 2017 American Music Awards last week with chopped-off, bright blonde hair. The new hue—which she paired with a form-fitting, all-leather dress with zipper detailing from Coach—was labeled “Nirvana Blonde” by her hairstylists of seven years Riawna Capri and Nikki Lee of Nine Zero One Salon, whom she trusted with the drastic change.

Capri had shared the look on her Instagram post —“‘Killin’ em with Blondness’ #SelenaGomez rockin’ her new #NirvanaBlonde #90sChic. A very patient color change and cut”— and now we know just how patient the “Wolves” singer and her team were.
